FIELD

The subject disclosure relates to robotics and more particularly to a biomimetics based robot and simulation.

BACKGROUND

Robotic systems to date have produced primarily machines that bear little resemblance to human beings. Part of the reason for non-humanoid approaches to robot builds is the difficulty in replicating human balance and coordination in machine language that is translated into mechanical movement. For example, with few exceptions, robots typically employ quadruped or track systems to move. It has been a difficult challenge to construct quadruped systems that can maintain balance while walking. The internal elements, (for example, support bars, hydraulic systems, pneumatic systems, etc.) have been difficult to coordinate between the upper robot halves and the legs. Coordination is often a product of insufficient programming that is not seen until live testing.

Currently, simulation software predicts a desired movement rather than actual performance between robot elements. This can be an expensive approach since once the build is started, troubleshooting may result in costly redesigns of robot features.

The result has been robots that appear more mechanical than humanoid. While some recent attempts have produced humanoid looking features on robots, the challenges with movement and coordination persist.

In addition, there have been many challenges to constructing robots with artificial muscles that can replicate humanoid movement. Currently robots can produce either fast twitch or slow twitch movements but not both in coordination. One of the challenges lies in the design of artificial muscles. For example, some robots use pure hydraulic cable systems which provide linear movement unlike human movement. Examples can be seen on factory floor assembly lines. Other robots use artificial muscles based on electro-active polymer casings that are actuated by applying an electric field to the casing. While such an approach may work for an individual artificial muscle, a negative phenomenon is observed when such artificial muscles are positioned in abutment as real muscles would be in a muscular system. The electric field applied to electro-active casings creates a spillover effect onto adjacent artificial muscles. As a result, electromagnetic interference may be observed causing the artificial muscles to operate out of sync with adjacent muscles and or fail altogether because the electric field signal applied is negated. Moreover, artificial muscles relying purely on electro-active polymer casings suffer from fatigue and being overloaded easily by heavy loads because the polymers have relatively low tensile strength.

As can be seen, there is a need for a robot that moves and appears humanoid and for a process to predict the performance of robots accurately.

DETAILED DESCRIPTION

The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The appended drawings are incorporated herein and constitute a part of the detailed description. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, it will be apparent to those skilled in the art that the subject technology may be practiced without these specific details. Like or similar components are labeled with identical element numbers for ease of understanding.

Generally, embodiments of the subject technology provide a biomimetics based robot and a process for simulating robot functionality. Robots of the subject technology appear humanoid, mimicking human anatomy and move with human-like coordination.

As will be appreciated, some aspects of the subject technology disclosed address problems related to controlling artificial muscles so that the muscles have both a fast twitch and slow twitch capacity so that they behave similar to human muscles. Having both fast twitch and slow twitch acting muscles allow robots to move both quickly or slowly depending on the application as well as provide improved load capacity. Moreover, as will be appreciated, some aspects overcome the deficiencies associated with electro-active polymer based artificial muscles that when positioned in a stack or array, are subject to EMI from each other when energized thus causing these kinds of artificial muscles to contract out of sync.

Other aspects of the subject technology address simulating the performance design of biomimetic robots so that the robot anatomy may be refined prior to actual build. As will be appreciated, aspects are capable of calculating the twitch speed of virtual artificial muscles, the force impact on various points of the virtual robot anatomy, predicted locations of extremities of a virtual robot and may then adjust output to the virtual artificial muscles and machine learn from iterated calculations what the real world expected performance of the robot will be.

Referring to FIGS. 1A-1D, a biomimetics based robot 100 is shown according to an exemplary embodiment of the subject technology. The robot 100 may include artificial humanoid structures (for example, a skeletal system 110 comprising artificial bones 115, a muscular system 120 comprising artificial muscles 125, a circulatory system 175 (shown as high pressure side 175 _(H) and low pressure side 175 _(L)) and connective tissues (ligaments, tendons, etc.)) (not shown in FIGS. 1A-1D). The artificial bones 115 may be made from carbon fiber. Some embodiments may use 3D printing to produce the skeletal components. Elements of the skeletal system 110 may mimic many of the bones and their position in a human. The artificial muscle tissue may be made from a flexible material. In an exemplary embodiment, the artificial muscle tissue is a non-electroactive polymer, such as elastomer or thermoplastic urethane. Similar to a human, the muscle system 120 in the subject robot may support and control movement in the skeletal system 110. Connective tissues may be made from, for example, braided polyester. The connective tissues may connect for example, joints in the skeletal system 110. An artificial nervous system may be included in the form of wiring, sensors, and microcontrollers described more fully below.

Referring now to FIG. 2, a block diagram of a biomimetic robot component circuit 200 is shown according to an exemplary embodiment. The circuit 200 generally includes a circulatory module 210, a power supply module 230, a computing module 255 and a sensor section module 260 connected to each other through wiring or conduits as represented by the arrows leading from one element to another.

The power supply module 230 is wired to and powers each element requiring a power source. The power supply module 230 may include a battery pack 238, for example, a lithium polymer battery, a fuel gauge sensor circuit 244, and a battery shield 242. Some embodiments may include an electronic starter 232, an engine 234, (for example, an alcohol micro engine), and an alternator or a synchronous generator 236 coupled to the battery pack 238. The battery pack 238 may be charged with the micro engine 234 (using for example, gasoline, diesel, alcohol or other fuel), with the alternator 236 (or synchronous generator). Control of the starter 232 and engine 234 may be coordinated with a CPU 16.

The computing module 255 may include a CPU 16 (sometimes referred to as a processing unit) in connection with each microcontroller 250 which may coordinate simultaneous control of multiple artificial muscles 125 (or muscle groups) and the feedback from multiple sensors from the sensor module 260. Data coordinated by the CPU 16 may be stored and retrieved from a system memory storage 34. Some embodiments may include a display 24 integrated into the robot 100 while some embodiments may include a port to connect an external display 24 to interact with the CPU 16. Some embodiments may also include a port for accessing a telecommunications network and to interface with a general computing device (described more fully below in FIG. 7) for software/firmware updates, to read data, and control functionality of the robot.

The circulatory module 210 includes a plurality of artificial muscles 125, which may be controlled for contraction by the other elements in the module 210. In an exemplary embodiment, the artificial muscle 125 may be contracted and relaxed by sending heated/cooled fluid (such as a gas, liquid, or oil) into the artificial muscle 125 and/or by heating a filament (described below). A pump controller 212 may send fluid through either a Peltier heating element 214 or a Peltier cooling element 215. Fluid from the heating/cooling elements 214/215 may be circulated to a temperature controller 220, for example a 3/2 solenoid fluid temperature controller to mix fluid to provide the temperature needed to contract or relax the artificial muscle 125 to a desired load capacity. A valve controller 218, may control opening or closing of a valve 135 (FIG. 3A) such as a solenoid to control retention or release of fluid from the artificial muscle 125. The temperature controller 220 may generate two temperatures to be pumped during repetitive motion such as walking. A cold fluid is pushed into relaxing artificial muscles 125 (see for example FIG. 3B) and a hot fluid pushed into contracting artificial muscles 125 (see for example, FIG. 3A) and vice versa depending on the cycle. A 50/50 mix of hot and cold fluid may be pumped into the artificial muscles 125 for medium contraction. The mix may then be divisible in quarters for 75%/25% contraction, etc. depending on the calculated load needed for movement. For sake of illustration only a single artificial muscle 125 is shown however, some embodiments may employ a multiplexor 216 to coordinate signals from a microcontroller 250 in the computing module 255 to the various artificial muscles 125 (or muscle groups). Some embodiments may include a microcontroller 250 dedicated to each muscle group.

The sensor module 260 may include a network of various sensors distributed throughout the robot 100 and wiring connected back to the CPU 16. A multiplexor 217 may coordinate feedback signals received from the various sensors and return signals provided by the CPU 16. Sensors may include force sensors 252 (for example force resistive sensors/resistors, stretch sensors 254 (for example strain gauges or resistors), a range finding sensor, a gyroscope and/or accelerometer, and a camera 266. The range finding sensor may be for example, LIDAR based. The range finding sensor may detect obstacles in the robot's path using range/distance/motion sensory. The combination of the LIDAR range finding and video source/camera 266 may be used for perception to setup up pathfinding input. In some embodiments, the robot 100 may speak with a chatterbox upon detected motion. In addition, detected objects may trigger the robot 100 to move its neck/head/eyes to follow objects using tracking. As will be understood, more than one sensor of each kind may be present in the robot 100 but for sake of illustration, only a single occurrence is shown.

FIGS. 2A-2C show examples of sensor positioning on skeletal points and proximate connection points between muscle tissue and skeletal structures. Sensors may detect for example, force applied to a skeletal point, acceleration (for example when a body part is moving), and stress force on the connection between muscle/connective tissue and an associated bone or joint. A number of examples of locations for sensors are shown however, for sake of illustration, many more locations have been omitted and it will be understood that more sensor locations will be present on the robot 100.

Thus, the contraction/relaxation of artificial muscles 125 may be coordinated to cause for example, one leg to lift from the ground and simultaneously move forward (step) while the other leg supports the remainder of the skeletal structure on the ground. Sensors in the stepping leg may sense for example acceleration forward (or backward), the rate of fall toward the ground, the amount of strain placed on artificial muscles 125, a strain on attachment points to artificial bones 115 (or joints), and changes in forces of impact indicating contact with the ground. The feedback from these sensors may be provided to the microcontroller 250 and CPU 16 to control additional movements to the stepping leg and the remainder of muscle groups in the robot 100. For example, feedback from the gyroscope/accelerometer which may be placed proximate skeletal extremities may indicate to the CPU 16 whether movement is occurring at a rate that needs adjustment (for example, a foot is stepping down to quickly or too hard). As may be appreciated, the stepping movement is only one example of movement possible by the subject technology and many other coordinated movements are now thus possible.

Referring now to FIGS. 3A-3B, an artificial muscle 125 is shown according to an exemplary embodiment. FIG. 3A shows the artificial muscle 125 in a contracted state (flexed). FIG. 3B shows the artificial muscle 125 in a relaxed state (unflexed). The artificial muscle 125 may include a flexible casing 130, which may be for example, an elastomer. In an exemplary embodiment, the flexible casing 130 is a non-electroactive polymer. A high pressure side 175H conduit 143 may define an inflow side of a fluid channel that extends throughout the length of the flexible casing 130 to a low pressure side 175L conduit 149. Some embodiments may include a valve 135 (for example a solenoid valve) positioned proximate at least one of the conduits 143 or 149 to regulate pressure pumped into the flexible casing 130 (as described above with respect to FIG. 2). In an exemplary embodiment, a filament 140 may be coupled to opposing ends of the flexible casing 130. The filament 140 may for example be connected to respective conduits 143 and 149 by anchors 142. The filament 140 may be for example a nylon filament. The filament 140 may be twisted, wound, braided, or meshed.

As will be appreciated, the actuation of the flexible casing 130 increases the speed or fast twitch of the artificial muscle 125 while the filament 140 provides load strength. In operation, the flexible casing 130 may be filled with hot, cold, or mixed temperature fluid to contract or relax the artificial muscle 125. As the PSI increases the casing 130 contracts for the quick twitch. The stronger filament 140 may take over the bulk of the load when the output needed may overload the strength of the flexible casing 130. The valve 135 may be closed when for example hot fluid is pumped in to the fluid channel to expand the walls of the casing 130. The filament 140 also heats up with the heated fluid and shortens in length pulling the opposing walls of the flexible casing 130 it is connected to closer together. The valve 135 may be opened to release heated fluid and cooled (or cooler) fluid may be pumped into the flexible casing 130 to relax the walls of the artificial muscle 125 to return to a default or unexpanded state. The filament 140 also stretches back to its default length as it is exposed to cooling fluid and the opposing walls of the flexible casing 130 it is connected to are drawn back outward away from each other or straightened out. During a cycle, the filament 140 oscillates in length proportional to the temperature of the fluid and proportional to the PSI acting on the walls of the casing 130. As will be appreciated, the use of the flexible casing 130 and heated fluid helps provide “quick twitch” action because the flexible casing 130 can expand and relax responsively to changes in pressure. The filament 140 provides support to the flexible casing 130 because the filament 140 has higher tensile strength and exceeds current load capacity of organic real muscles and contracts more with more force. Thus, when a “slow twitch” action is needed, the filament 140 may provide the bulk of the force to the application when fast twitching is not necessarily the priority. Thus, the flexible casing 130 is spared from fatigue and damage from routine fast or slow twitch based movement.

Referring now to FIG. 3C and FIG. 4, an array 150 of artificial muscles 125 along with a circulation circuit are shown according to exemplary embodiments. An example of a circulation pattern of fluid is shown in FIG. 3C which represents the high to low side movement of fluid through the artificial muscles 125. As described earlier, the pump 212 pumps fluid through heating element 214 or cooling element 215 and solenoid temperature control mixers 220 depending on whether an array 150 should be contracted or relaxed. As will be appreciated, skeletal portions of the robot 100 have opposing muscle arrays 150 to provide counter forces during movement, which help provide the biomimetic result. For example, an artificial leg may have artificial quadriceps and an opposing array 150 of artificial hamstrings. Aspects of the subject technology pump heated fluid into an array 150 a to contract the artificial muscles and synchronously, pump cooled fluid into an opposing muscle array 150 b. While the array 150 is shown with artificial muscles 125 stacked in parallel, it will be understood that this is for sake of illustration and that the artificial muscles 125 may overlap similar to the arrangement of muscles in a human body (for example as shown in FIGS. 1A-1D).

In addition, it will be further appreciated that embodiments using non-electroactive polymers overcome the deficiencies of some prior art artificial muscles that use electro-active polymers for artificial muscle arrays. Non-electroactive polymers preclude the phenomena of electromagnetic interference that spills over from electro-active based artificial muscles into adjacent electro-active based artificial muscles. The artificial muscles 125 of the present disclosure mechanically support adjacent artificial muscles 125 without electromagnetic disruption. Thus, coordinated actuation of the artificial muscles 125 in arrays 150 is achieved with expected processor based synchronization.

Referring now to FIGS. 5a and 5b , a method 500 of simulating robotic physics is shown according to an exemplary embodiment of the subject technology. The method 500 is shown in block form describing the general steps/actions for simulating performance of a robot design and construct in a virtual world prior to build and/or introduction of a new movement into the robot's stored memory. In general, the method 500 uses stored motion capture video of for example human motion to simulate movement frame by frame for a robot design. A physics 3D model, motion capture data, and environmental variables may be input 505 into the simulation engine. The simulated movement of artificial muscles may be targeted 510 to replicate the motion retrieved from motion capture data (of for example human movement). Simulated movement may be based on the amount of pressure/temperature applied to artificial muscles and the cycle rate actuation. Movement may be evaluated frame by frame to replicate the targeted data. The targeted movement performance may be evaluated by changing 515 the virtual environment. A virtual clock may be accelerated 520 to speed up the frame by frame evaluation. The engine may machine learn 525 the best possible muscle contraction strength for a particular instance in time and for a particular motion. The engine may determine 530 whether the machine learned motion from block 525 has been resolved virtually for the particular moment in time. If there is no resolution at block 525, then the engine may repeat 535 the machine learning step of block 525. If resolution is determined, the engine may determine 540 whether an entire cycle of motion has been trained for use in the robot. If not, the process returns to block 545 to move to the next frame for analysis. If the entire cycle is trained, the learned motion may be exported 540 for storage in the real robot's system memory storage or embedded in the real robot's CPU and/or microcontroller(s). The learned motion data may be recorded 555 and compared to a performance of the real robot using the stored motion data. The recorded data and comparison data may be stored 560 in a simulation system database. Based on predetermined criteria, the engine may determine 565 whether the performance results by the real robot are satisfactory. If unsatisfactory, the engine may machine learn 570 variations in real world robot performance as compared to virtual physics. Based on the machine learned results of block 570, the engine may adjust 575 the physics simulation engine and return the process to block 525 to loop the machine learning step until optimized muscle contraction performance is reached.

If satisfactory, in some embodiments, the real world biomimetic robot may be physically moved to a new location/environment. In the new location, the method may use either the simulation engine loaded onto a computing device or cloud computing system to learn new optimized artificial muscle movement for the new location or a copy of the simulation engine may be loaded into the robot's memory for learning 580 the new environment. If using the computing device outside the robot, the simulation engine may upload a new virtual environment into the simulation engine and may re-target 585 the movement of virtual artificial muscles in the virtual environment. The process may repeat as described above for reaching the new target performance and/or optimized muscle contraction of artificial muscles for use in the new location.

In exemplary embodiments with the simulation engine loaded into the robot's memory, the robot may identify it is in a new location. The robot may determine whether location data exists in storage and whether or not new muscle performance data may need to be generated. If location data does not exist, or for example, the location has been modified from a previous stored file, the robot may generate a virtual environment replicating the current location. In some embodiments, the robot may wirelessly access a network, a cloud computing network to process simulation of the robot's artificial muscle performance in the virtual environment. The robot may re-target 585 the performance criteria for the artificial muscles in the virtual environment and once the target is reached (via looping through the steps described above), may store the control settings in its memory for use with the real world artificial muscles that make up the robot. As will be appreciated, in some embodiments, the aspects of the method allow the biomimetic robot to perceive the environment around it and increase its learning of how to move through the loop of continuously machine learning and optimizing control and performance of its artificial muscles to move in the environment. While in some embodiments, the robot may be aided by the operator simulating a first environment and then a second environment and so on to upload into the robot's memory the data it needs to move in some initial settings, eventually the robot may be able to move into an arbitrary location, capture an image of the location, generate a virtual simulation of the location, and simulate its own movement in the location to control its muscles accordingly for real world movement in the location.

Referring now to FIG. 6, the sub-process 570 of machine learning variations in real world robot performance versus virtual physics is shown in more detail according to an exemplary embodiment. The sub-process includes comparing 582 the real world location of an extremity on the real robot to an expected location via simulation. The location of the extremity may be gathered by sensor data for example as described with respect to FIGS. 2 and 2A-2C. A determination 584 is performed on whether the real world location of an extremity on the real robot to an expected location is within a threshold value.

If the determination is within the threshold value, the engine increases 586 the value of certainty of motion in the simulation. A subsequent determination 588 is performed on whether all points in motion space for the real robot are checked within the frame being analyzed. If not, the next extremity location may be checked 590 and the sub-process may return to block 582. If all points have been checked, then the analysis may move to the next frame (for example, block 545 in method 500).

If the determination in block 584 is not within the threshold value, then muscle contraction velocity may be adjusted 592 within the simulation engine. The actual motion of the real robot extremity may be logged 594 and the certainty of motion for actual resultant motion may be increased. The sub-process may then reiterate the comparison performed in block 582 with the adjusted data.

Referring now to FIG. 7, a schematic of an example of a computer system/server 10 is shown. The computer system/server 10 is shown in the form of a general-purpose computing device. The computer system/server 10 may serve the role as the machine implementing for example the functions in a virtual setting of running physics based simulation, storing motion capture video, comparing simulation results to captured motion video, adjusting muscle control to mimic/match motion capture video, and storing muscle control data for simulated muscles. The computer system/server 10 may in some embodiments serve the role as the machine implementing for example the functions in the real robot of providing instructions for muscle control, calculating sensor feedback and adjusting to muscle control.

The system memory 28 may include at least one program product 40 having a set (e.g., at least one) of program modules 42 that are configured to carry out the functions of embodiments of the invention.

Such communication can occur via Input/Output (I/O) interfaces 22. Alternatively, the computer system/server 10 can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via a network adapter 20. As depicted, the network adapter 20 may communicate with the other components of the computer system/server 10 via the bus 18.
